#### `convert(src, dst)`
#### `process(src, dst)`

The convert function performs a pixel conversion. The `src` argument is the input pixels in the format specified in the constructor. The input pixels are stored either in an `ArrayBuffer` or a `HostBuffer`. The `dst` argument is where the output pixels will be returned. It must be an `ArrayBuffer`.
The `process` function performs a pixel conversion. The `src` argument is the input pixels in the format specified in the constructor. The input pixels are stored either in an `ArrayBuffer` or a `HostBuffer`. The `dst` argument is where the output pixels will be returned. It must be an `ArrayBuffer`.

```js
converter.convert(inputPixels, outputPixels);
converter.process(inputPixels, outputPixels);
```

The caller of convert is responsible for allocating a large enough output buffer. The `Bitmap.depth` function is useful for this calculation.
